Abstract: 926,279. Machine tool details. WARNER & SWASEY CO. March 14, 1962 [April 24, 1961], No. 9786/62. Class 83 (3). [Also in Group XXIX] A drive system for a movable member, such as the slide 10 of a machine tool, comprises an actuator 13 having a piston 42 and cylinder 11, one of which is connected to the member to reciprocate the latter, a change-speed port 26 intermediate the ends of the cylinder and adapted to be covered and uncovered by the piston to change the speed of movement of the member, a valving portion 44 on the piston for co-operation with the port, which portion has a cylindrically curved land closely fitting the cylinder for less than 360 degrees and an oblique control edge 46, and means supporting the piston and cylinder for relative angular adjustment about the axis of the actuator to position a particular portion of the control edge for cooperation with the port upon reciprocation of the piston to determine the axial position at which the port is covered to change the speed of the piston. The control edge 46 may be formed by a flat 48 provided on the piston and a diametrically-opposed flat 49 is provided to balance the forces acting on the piston. A rod 15 extends from the piston and is connected by a knob 40 to an apron 17 of the slide whereby the piston can be rotated to select the portion of the control edge which is to co-operate with the port 26. Fluid pressure from a pump 36 is supplied to one or other of ports 20, 23 at the ends of the cylinder under the control of a valve 35, the port 23 being connected by a check valve and throttle assembly 31 to the valve. A check valve 28 permits flow only from the port 26 to the valve 35. After the piston has been rotated to its selected position, the valve 35 is operated so that fluid from the pump passes to the port 20 to move the piston to the right at a rapid speed, fluid from the right of the piston being exhausted through ports 26 and 23. When the control edge covers the port 26, the fluid to the right of the piston can only exhaust through port 23 at a rate determined by the throttle in the assembly to change the speed of the piston. When the valve 35 is moved to its alternative position, the check valve in the assembly 31 opens to permit full flow to the port 23 and rapid return movement of the piston; the check valve 28 renders the port 26 inoperative during the return movement. In an alternative embodiment, the control edge is formed by a curved cut-out portion in the piston.

Abstract: 1,254,963. Welding by fusion. REDEMAT S.A. 24 Feb., 1969 [1 March, 1968], No. 9807/69. Heading B3R. . In arc, e.g. MIG(CO 2 ), or electro-slag welding with one or more consumable electrodes, metal transfer is monitored and, if desired, controlled during the welding process by electronically determining the actual, frequencies of class values (e.g. amplitude, time) of at least one variable welding parameter (e.g. voltage, current), electronically determining a distribution curve of said actual frequencies, and electronically comparing said actual frequency curve with a desired frequency curve. In Fig. 3 (not shown), the class values are short circuit duration. Deviations may be signalled electrically, electromechanically, optically or acoustically, e.g. they may be marked on the weld seam, as by a laser beam, or recorded by a tape recorder running synchronously with the weld. A printer or X-Y recorder may be used as a display or recording device. Deviation signals may be fed back to the welding apparatus so as to act in a deviation reducing manner. As shown, welding voltage is transformed by an analogue-digital converter ADU into digital information which is passed to a classifier K, the latter summing up the frequencies of class features and storing them at KS. The information stored at KS is passed to a comparator V, deviation being delivered to marker M. The deviation may also be delivered to a correction control R acting on a welding machine SM. In means allied to the invention, Fig. 1 (not shown); the information stored at KS is'passed through a control (St) for printing at (Dr) and/or recording as a curve on an X-Y recorder.
